Mrs. Marie Graskamp of Milwaukee shows the different positions one might assume when entering the bomb shelter in Milwaukee September 3, 1958. This circular entrance is about three feet in diameter. This is the entrance (according to the builders) that would connect to the cellar of a home assuming the shelter was in the ground for added protection. If a bombing should occur, all members of family would proceed to the cellar and then through the circular port into the shelter. (Photo by AP Photo)

A file photograph dated 07 January 2006 and released by Greenpeace, showing the Yushin Maru, a factory ship in a Japanese whaling fleet, injuring a whale with it's first harpoon attempt. A UN court in The Hague on 31 March 2014 halted Japan's much-criticized whaling programme, ruling that it contravenes a 1986 moratorium on whale hunting. Japan must end its 'research whaling' programme, the International Court of Justice (ICJ) said. Japan said the programme was for scientific research and permitted under international conventions. Australia had brought the case to the ICJ in 2010, charging that Japan was breaching international law by killing hundreds of whales every year for commercial purposes. Japan was “deeply disappointed” by the ruling, an unnamed government official was quoted by the Kyodo News agency as saying. But the official said Japan would stand by the ruling.
